Adam Scott clawed back in the second round of the US Open but still sits a distant 10 shots off a hot Martin Kaymer.

Adam Scott knows all to well how hard it is to sit on a large lead, ensuring the world number one has hope he can reel in German Martin Kaymer at the US Open Championship.

Scott made a significant second round move up the leaderboard at Pinehurst No.2 after producing his best round in a US Open, a three-under 67.

It was just the second time in 38 attempts he’s been in the 60s and the third time under par.

It moved the Queenslander to even-par for the tournament, and a tie for 14th, but a whopping 10 shots adrift of the man dubbed the Germanator.

Kaymer posted his second consecutive round of 65 to move to 10-under 130, the lowest total in US Open history through 36 holes.

He leads by six shots over American Brendon Todd (67) and is seven clear of Kevin Na (69) and Brandt Snedeker (68) who share third at three-under.

Kaymer, who won the lucrative Players Championship recently, was bogey-free and has played unconsciously good golf but Scott, with four birdies and just the lone bogey, at least gave himself a chance to do some damage over the weekend.

“There are so many talented guys and he’s certainly one of them and he’s confident enough after winning a big event already this year,” Scott said.

“So for him to come out today and back it up is super. If he does it for two more days, then we’re all playing for second spot.

“But we all know that US Opens get very difficult and if I can just somehow put together two really good rounds, maybe slowly but surely I’ll creep my way up towards Martin.”

Scott led the Arnold Palmer Invitational earlier this year by seven shots at the halfway mark before being run down on the final day and also led the 2012 British Open by four with four to play before being bested.

So the 33-year-old knows better than most the tournament isn’t over until the last putt drops.

“I think if I drew up my perfect plan right now, over the next 27 holes you would like to narrow the gap to less than half of what it is,” Scott said of his strategy going forward.

“Anything could happen over the last nine holes at a U.S. Open, so if I played great and he continues to play great, I think I can narrow that gap and hopefully feel like I’m in contention come the back nine Sunday.

“I’d hope if I can play my way into the rear view mirror with nine to go it will be fun to put some pressure on.”

Jason Day, like Scott, turned around his tough opening round with a better performance, shooting 68 to move to one-over and a tie for 20th. Aaron Baddeley joined him after he slipped slightly with a 71.

For the other eight Australians it was a US Open to forget as they all missed the cut.

Matt Jones (72) missed by one shot at six-over as did Rod Pampling after a 73, John Senden struggled to a 76 to be seven-over, equal with 2006 champion Geoff Ogilvy after the Victorian carded a 74.

Brady Watt (74) finished at 11-over on debut in a major while fellow first-timer Aron Price (74) and veteran Robert Allenby (73) finished well back at 12-over.

Amateur Oliver Goss, who is expected to turn professional soon, had a nightmare day, shooting an 83 to plummet to 14-over.
